我正在尝试使用rails api-ony应用作为后端,将React js作为前端。我正在使用axios发送/接收请求。最初我甚至无法登录,经过大量谷歌搜索后我遇到this gem关于 CORS ,它解决了我的POST请求错误。
 当我在rails应用程序中执行POST请求时,我能够成功登录,并且我得到令牌作为回报(适用于POSTMAN应用程序)。现在,当我执行GET请求并使用反应应用程序将该令牌作为标题传递时,它继续向我发送401 Unauthorized error,然后在经过大量谷歌搜索后再次看到this SO post。它没有解决这个问题。我错过了什么?请介绍一下这个问题的原因。 这是application_controller.rb:

class ApplicationController < ActionController::API
    include ActionController::MimeResponds

    before_action :authenticate_request, :current_user, :cors_preflight_check
    attr_reader :current_user

    #before_filter :current_user, :cors_preflight_check
  after_action :cors_set_access_control_headers

# For all responses in this controller, return the CORS access control headers.

def cors_set_access_control_headers
    headers['Access-Control-Allow-Origin'] = '*'
    headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
    headers['Access-Control-Request-Method'] = '*'
    headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'
  headers['Access-Control-Max-Age'] = "1728000"
end

# If this is a preflight OPTIONS request, then short-circuit the
# request, return only the necessary headers and return an empty
# text/plain.

def cors_preflight_check
  if request.method == :options
        headers['Access-Control-Allow-Origin'] = '*'
        headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
        headers['Access-Control-Request-Method'] = '*'
        headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'
    headers['Access-Control-Max-Age'] = '1728000'
    render :text => '', :content_type => 'text/plain'
  end
end

    require 'date'
            require 'json'
            require 'groupdate'

    end
end

在我的反应应用程序中,我有这个:

import React, { Component } from 'react';
import '../App.css';
var axios = require('axios');

class Login extends Component {
  constructor(props){
    super(props);
    //this.state = {isToggleOn: true};
    this.loadDashboard = this.loadDashboard.bind(this);
    this.handleOnSubmit = this.handleOnSubmit.bind(this);
  }

  loadDashboard(token){
    axios({
      method:'get',
      url:'http://localhost:3000/api/dashboard',
      Authorization: {
        Authorization: token,
      },
    })
     .then(function (response) {
       console.log(response);
     })
     .catch(function (error) {
       console.log("Error in loading Dashboard "+error.response.status);
     });
  }

  handleOnSubmit = () => {
     console.log("submittwed");
     axios({
       method:'post',
       url:'http://localhost:3000/authenticate',
       data: {
         email: 'test@mail.com',
         password: 'apple'
       },
     })
      .then((response) => {
        var token = response.data.auth_token;
        console.log(token);
        this.loadDashboard(token);
      })
      .catch(function (error) {
        console.log("Error in login "+error);
      });
   }

  render() {
    return (
      <div>
         Username: <input type="email" name="fname" /><br />
         Password: <input type="password" name="lname" /><br />
         <button onClick={this.handleOnSubmit}>LOG IN</button>
      </div>
    );
  }
}

export default Login;

  • 其他人是否面对过类似的事情?
  • 我该如何解决这个问题?
  • 是否有更少杂乱/更好的方法?

请帮我解决这个问题。

您缺少要发送到api电话的headers密钥。

axios({
  method:'get',
  url:'http://localhost:3000/api/dashboard',
  headers: {
    Authorization: `Bearer ${token}`,
  },
})
  .then(function (response) {
    console.log(response)
  })
  .catch(function (error) {
    console.log("Error in loading Dashboard "+error.response.status)
  })
